. FILM-REWINDING DEVIQE.

Application filed August 15, 1911.

T0 all whom it may concern Be it known that I, CHARLES V. FooTE, residing at N ephi, in the county of Juab and State of Utah, have invented certain new and useful Improvements in Film-Rewinding Devices, of which the following is a specification.

My invention. relates to `improvements in'moving picture machines, and has for its leading object the provision of an improved attachment therefor for use in rewinding one film ready to be again displayed while another film is being unwound and thrown onto a screen by the machine.

The further object of my invention is the provision of an improved film rewinding atnioving picture machines which will be driven by the power operating the kinetoscope to rewind the .film at 4.the same time that another film is being displayed and which will be provided with means for automatically stopping the re-" winding either when the film is entirely reivound or upon breaking of the film rewound.

Other'objects and advantages of my im- I provedfilm rewinding attachment for mov' ing picture displaying machines` will be readily apparent by reference to the following description taken in connection with the accompanying drawings and it will be understood` that I may make modifications in the specific structure shown and described .within the scope of my claims without departing from or exceeding the spirit of my invention.

`Figure l represents a side elevation of a' motion improved rewinding attachment. Fig. 2 represents an enlarged side elevation of the upper portion of myv attachment. Fig.' 3 represents an enlarged side elevation'v of the rewinding box and parts secured thereto. Fig. a represents a sectional view on the linev 4% of Fig. l. Iiig.` represents an enlarged side elevation of the device as illustrated in Fig. 3, but showing ythe'pa'rts shifted -to apply the brake and throw out the clutch. Fig. 6 represents a sectional view on the line 6*(5 of Fig. 1. Fig. 7 represents a View of the interior of the. rewinding box showing a pair of film reels in posi-.

of said figure, and Fig. 10 represents a sectional view on the line 10-10 of iFig. 2. In the drawings in which similar characters are employed to denote corresponding parts throughout the several views, the nunieral l designates the table or supporting picture .machine have ing the suitably braced legs 2 and having secured thereon the guides 3 for the lantern 4. Secured at the front end of the table l is the suitably driven film displaying mech. anism 5 including a shaft 6 bearing a pulley 7 around which passes a belt 8 for driving the film winding shaft 9 which serves to draw downward the film which is being displayed.A The lilm drawn down by the rotation of the shaft is wound upon a reel lO but it is necessary to unwind the film from said roll onto another reel before the film may be again displayed, and the object of my invention is' to provide means for readily Winding a film onto a reel from which it may be displayed as thes reel l0 is receiving another ilm. To attain this result I secure to the ioor 11 on which the supporting legs rest the bracket legs l2 which are secured to the film rewinding boi: 13 having journalcd therein the reel bearing shaft 14 and the rewinding reel nearing shaft l5. To rotate the shaft l5 and thus the reel 17 locked thereon by the ,usualv locking 18, i secure on the outer end of the shaft l5 the groove pulley 19 around which passes the crossed belt20 also passing around the grooved pulley 2l which is rotatably mounted on the end of the )shaft 6. Said pulley 2l has the clutch collar 22 projecting from the innerface thereof for engaging the clutch 23 secured on the shaft G-,to to rotate with the shaft, a projecting from the opposite ley to control the clutch. To shift 2l and thus to operate the clutch I shift collar 24 face of the 'pulthe pulley plate cause the pulley adjust- I ably secure to the side of the table the bracket 25 having rotatably supported by its upper end the shift rod 26 having a yke 27 engaging the shift collar 24 and having the arms 28 and 29 projecting therefrom for rocking the rod to shift the pulley. vA lever 30 is secured to the arm 28 and extends across the .table lr for rocking the rod 26 to operate the clutch.

To automatically operate the clutch, I have providedvmy combined tension or brake device and clutch shifter. Pivoted to oneof the bracket legs 12 is the rear end of the brake lever 31 having a sleeve portion 32 in which is adj ustably held the controlling rod 33 locked in position by the set screw 34 Said brake .lever has secured to its under face the vbrake against the brake drum 36 lsecured on the end of the shaft 14. To force'the lever downward onto the brake drum, I secure to the leg 12 the disk 37 having the ratchet teeth 38; while wou-nd on the bolt 39 is a helical -spring 40 having a projecting end 41 bearing down upon the brake lever and having its other end 42 engaged by one of the teeth 38,the engagement of said end on diiferent teeth 38 adjusting the tension ofthe spring.

Secured on the forward end of the rod 33 is the sleeve 43 bearing the slotted guide portion44 having a shoe 45 adapted to normally rest againstl and servel as a brake on the pulley 19.- .The portion of the belt 20 drawn upward lby the rotation of the pulley 21 passes between the furcations of the guide 44 and as the belt is tensed forces the guide 44 upward to relieve the brake drum and the pulley 19 from the pressure thereagainst. To keep the belt stretched tightly over the pulleys as the guide 44 is raised, I pivot to one of the legs 12 the bell crank 46 having one arm connected by the link 47 with the guide 44, while the other arm of the bell crank is provided with a guide ring 49 through which the looser portion of the belt passes downward. As the guide 44 is raised it serves to swing the bell crank 46 on its pivot to shift the ring 49 and thus to keep the belt tight as is clearly shown in the drawings. It will thus be seen that as long as there is a resistance to the rotation of the pulley 19 on account of its shaft winding a film the upwardly extending portion of the belt 20 4will be kept tenseto hold upward the forward portion ofthe rod 33 but when the film is entirely wound or the machineis stopped there being no resistance to keep the belttense the spring 40 will serve to swing the rod downward. To shift the pulley 21 to throw out the clutch upon the downward movement of the rod 33, I employ the rod 50 which is pivoted at its upper ends to the arm 29 of the rod 26 and has at its lower end the loop 51 through which the rod 33 passes. As the rod 33 swings vdownward it strikes the bottom of the loop 51 and draws' the rod 50 downward ,to throw out the clutch. The spring 40 continues the movement of the rod 33 to simultaneously apply the brakes to the brake drum 36 and pulley 19 to stop the feed and rewinding reels.

shoe 35 adapted to bearl If it is desired to supplement the action of the descent of the rod 33 in checking the movement of the belt 20 by throwing out the clutch, I may rotatably engage in the side of the rewnding box 13 the spindle 52 having on onel end the rock arm 53 pivoted to the depending end of the rod 50 and having on the other end of the crank portion 54 adapted to be engaged and moved upward by contact therewith of the clip on the end of the picture film, the upward movement of the crank 54 drawing the rod downward to throw out the'clutch.

From the .foregoing connection with the accompanying drawings the construction of my improved lm rewinding attachment machines will be readily apparent and it will be seen that I have provided an extremely satisfactory and efficient device of this character which may b e easily secured upon any ordinary motion picture machine of either manually driven or power operated type and which *will serve to satisfactorily rewind one film while another is being displayed by the machine and which is so constructed as to automatically. throw out the clutch of the rewinding attachment when the film has been entirely wound, when the machine is stopped, or when a break `occurs in the film to be rewound, thus preventing damaging of the rewound film by whirling of the same after it has been rewound.

I claim:

rlhe combination with a rotating shaft, of a pulley having a part loosely mountedon the shaft, a clutch for operatively connecting the pulley and shaft, 'a rewinding boX having feed and rewinding shafts rotai tably mounted therein, a drum for the feed shaft, a sheave secured on the rewinding shaft, a cross belt connecting the pulley and sheave a rod positioned between the rewinding and feed shafts, brake shoes mounted upon the ends of the rod and adapted to engage the sheave and drum, respectively, a tensioning device carried by one end of the rod and engaged by the crossed belt, whereby tensioning of the belt will shift the brake shoe out of engagement with the sheave and means for throwing out the clutch upon slacking of the belt. v A l In testimony whereof I aiiix my signature in presence of two witnesses. y
